I installed it on a CR-48 and did NOT have to do the initial setup, the user accounts were retained.

The only issue I've got is that the buttons for my X-Notifier, Adblock, and Google Voice always appear as if they are depressed. It's kind of annoying but so far stability is excellent and everything is 100% functional.
